ADJUSTABLE DEFLECTOR FOR HOT-AIR FURNACES.

Specification of Letters Patent. 7

Patented Oct. 5, 1920.

T 0 all to 710m it may concern Be itknown that I, AnN'r HENDRICKSON, a citizen of the United States, residing at Minneapolis, in the county of Hennepin'and State of Minnesota, have invented certain new and useful Improvements'in' Adjustable Deflectors for Hot-Air Furnaces; and I do hereby declare the following to be a full,

clear, and exact description of the invention, such as will enable others skilled in the art to which'it appertains to make and use the same.

My invention relates particularly to a hot .worl:s in an opening formed in the wall just above the floor register.

As preferably designated, the deflector is made up of extensible, deflecting wings hinged at their upper edges to the partition wall and have a detachable, interlocking engagement in their free lower edges, so that the two deflecting wings may be adjusted either simultaneously or independently,'at will.

As a still further feature of novelty, this deflection may be applied in connection with a wall pipe set intothe partition wall, all

that will here and aftermore appear.

The invention is illustrated in the accompanying drawings, wherein like characters indicate like parts throughout the several views. Referring to the drawings:

Figure 1 is an elevation, showing portions of the floor register, the deflector and air pipes and some parts being broken away;

Fig. 2 is a fragmentary view chiefly in elevation but with the floor register sectioned, showing particularly the deflector and its supporting frame;

Fig. 3 is a section taken approximately on line 8-3 of Fig. 2;

Fig. 4 is a detail in section on the line 4-4 of Fig. 3, some parts being broken away;

Fig. 5 is a view, chiefly in plan but with someparts n horizontal section on line 55. of Flg. 1; and-- Flg; 6 is a vertical section taken on the line 6-6 of Fig.- 5.

The numeral 7 indicates a flat perforated plate that affords a floor register and has a depending flange 7 set into the floor 8.

The numeral 9 indicates the hot air stack and 'the numeral 10 the cold air returning stack 'ofthe so-called pipeless furnace. The air stack 9 is within the stack 10 and the former is cylindrical, while the latter is square in cross section and at its upper edge fits into the flange 7 of the floor register 7 The numeral 11 indicates a partition wall that extends across the register 7, but is cut away, above the sameand is provided at its cut away portion on both sides of the wall, with a rigidly attached rectangular frame 12.

Connected at their upper edges, by hinges 13, toithe horizontal upper portion of the frames 12, are vertically, extensible deflector wings, each wing being made up of two sections 14; and 15. The upper sections 14: of these deflecting wings are directly attached at their upper edges to the hinges 13,. At their side edges, the wing sections lihaveinturned flanges 14 that are overlapped-by and slide within inturned U-shaped flanges 15 of the respective'lower wing sections 15. One of the lower wing sections 15 is provided with a Ushaped flange 15 at its lower edge, that is adapted to receive the lower edge of the other wing section 15, (see Figs. 3 and 6) to thereby lock together the lower edges of the two deflecting wings, so that they will have common lateral sliding movement over the register 7. Preferably the lower wing sections 15 are provided with finger pieces 15 by means of which they may be raised or lowered and by means of which the two wings may be either simultaneously or independently adjusted.

When the two wings are made very long,

it may he sometimes desirable to slidably -flector made up oftwo wings-worlzing in the wall opening and hinged tothe wall ,on I

thereof than at the other.

located in the wall and provided with cold air return channels 19. This wall pipe is adapted to convey hot air to an upper room and return the cold air therefrom.

The hot air register may be locatedvin any.

' defiectedinore or less from the'one side to j the other side or" the partition wall. Under the lateral. adjustments of the deflecting wings, the said wings are automatically extended and contracted so that they will al-' ways; maintain contact with the register 7.

When the two wings of thedeflectorai'e disconnected at the lower edges, the said wings may be independently adjusted; so as to vary the. amount of air delivered on the opposite sides of the partition wall, and so as to 'varyalso the amount of, air that will be delivered to the wall pipe. Thus, it will be-seen that the Various adjustments serve to regulate the distribution of'heat as between the rooms on the opposite sides of-the partition wall and as between t the lower rooms and'an upper room. It will be, of course, understood that in the arrangement illustrated, the left hand lower wing of section'15, may be interlocked to or disconnected from the lower section 15 of the right hand wing,-'simply by giving the said lower section'of the lefthand'wing a slight ver-. tical movement; Y

'WhatIclaimis; I a

1. The combination with a hot air floor register and a partition wall having an opening overlying said register of a deopposite sides thereof, said wings being slidably extensible in a vertical direction and having. detachably engageable portions which, when engaged,oonnect-the two wing sections for simultaneous adjustments. 3. The combination with a hot air floor register and a partition wall having an opening" overlying said register, of a defiector made up of two wings working in the wall opening and hinged to the wall on opposite sides thereof, said wings being slidably extensible in a vertical direction, anda hotair pipe located in said partition wall' and opening into the space between the upper portions of said wings. v
